RAF Chins
I've done it, don't like to do it...and prepare myself for the worst...but when you take in a chinchilla that's being fed dog food...or hamster food...or even just Charlie Chinchilla...sometimes it has to be done. Your chins are young, so especially susceptible. If you can avoid it, I would, if not...keep a close eye on intake and output and behavior.
